' WINDOW LATCHING DEVICE Filed April 8, 1948 Patented Jan. 8, 1952 UNITED srArEs PATENT OFFICE WINDOW LATCHING DEVICE Arthur J. Underwood, Tra/er. Iowa. applic-anon April s, 1948, serial No. 19;':72

' (c1. ese- 262i 101mm. l

rihis invention relates to Window latching devices and more particularlyeto 4devices of lthat nature which are adapted for use with the casement type of window.

Windows of that type` are quite widely employed in the construction of farm `livestock buildings such as dairy barns, poultry houses and the like, one of the4 primaryreasons being that they may be opened inwardly `at the top to 'provide draft-free ventilation.

.It is a primary object of `my invention to provide a new and `novel device `for latching and securing windows .of that general nature in any one of a plurality of positions.

Another primary object of my invention is the provision of a latching device for the easement type of window which will permit quick and easy adjustment of the window to either closed, opened, or partly opened position and which will effectively secure the window in the desired position.

A further object of my invention is the provision of a device of this nature which may be manufactured at low cost and quickly and easily installed with the simplest of tools.

Other and further features and objects of the invention will be more apparent to those skilled in the art upon a consideration of the accompanying drawings and following specification, wherein is disclosed a single exemplary embodiment of the invention, with the understanding, however, that such changes may be made therein as fall within the scope of the appended claim, without departing from the spirit of the invention.

In said drawings:

Figure 1 is a View in perspective illustrating a latching device constructed in accordance with a preferred embodiment of my invention and showin.;r the manner of application to a easement window.

Figure 2 is an enlarged view in front elevation of the latching device shown in Figure 1.

Figure 3 is a view in vertical cross section of the window illustrated in Figure 1, showing the window as secured, by my latching device, in completely closed position.

Figure e is similar to Figure 3 but illustrates the window as secured in partly opened position.

Figure 5 shows the manner in which the same window may be extended to fully opened posif 2 in a windowopening 4out between ystuds II and I2. The sash Vis supported by the window 4sill I3 and voutward movement is prevented by means `of window stops or by the sheathing I4, all in accordance with common practice. The sash may be hinged to the sill I3 or may simply be set in place behind an inside window stop IlE.

The window sash Il) is illustrated in Figure l1 as secured in partly opened position by means ef the latching device indicated generally by the numeral II 'l `and which consists, in this preferred embodiment of my invention, of three main elements, the bolt I8. the bolt keeper yI9 and the latch plate 2 I.

The bolt I8 is formed 1in generally U-shape of rod which is preferably circular in .cross section, the spacing between the two 'legs 22 and 23 thereof being greater than the thickness of a standard wall stud (I2) by at least the diameter of the rod lfrom which the bolt is formed. The bolt is aiixed to the vertical exposed edge of the wall stud I2 by `means of the keeper I9 and Wood screws .24, the `keeper having a generally tubular, transverse recess lila therein Vfor the reception of the cross leg 26 of the bolt.

One leg 22 of the bolt is preferably attened for service as an operating handle, the other leg 23 having an end hook portion 23a thereof formed at right angles thereto and parallel to the cross leg portion 26. The hook portion 23a is adapted to engage the inner side of the sash as best shown in Figures 3 and 6, the adjacent leg 23 being of suitable length to urge the sash into tightly closed position when the bolt is turned as in Figure 3.

The latch plate 2l is generally rectangular in shape having one portion 2|a thereof apertured, as at 2 Ib, to receive wood screws 2l. The hookengaging portion 2Ic of this latch plate is olfset inwardly from the sash a distance substantially equal tothe thickness of the hook. The edge 2 Id is preferably bent inwardly for rigidity and when the latch plate is attached to the sash by the wood screws 2l, the reinforced edge 2Id is positioned horizontally away from the adjacent vertical edge Iiia of the sash a distance substantially equal to the thickness of the leg 23.

It should be here noted that the keeper I9 also is spaced from the vertical face I2a of the stud a distance substantially equal to the thickness of the bolt.

As hereinbefore explained, the latch is adjustable to three positions, any one of which may be secured by shifting the bolt laterally and rotating the handle. Figure 2 best illustrates the ,of similar nature.

d8a when the window is to be closed. At this' position, the long leg 23 of the bolt lies between the reinforced edge of the latch plate and the adjacent stud.

Opening of the window sash from the closed position to the position shown in Figure 4, is accomplished by raising the handle 22 of the' bolt until movement thereof is stopped by contact with the sash. Lateral movement of the bolt toward the latch plate engages the entire length of the bolt leg 23 behind the latch plate, thus securing the window sash..

Furtheropening of the sash to the position illustrated in Figure is accomplished by shifting the bolt as far as possible to the right or to the dotted line position indicated at I8b and then rotating the handle outwardly.

A window latch such as I have herein described has numerous advantages over prior art devices This device increases the utility of the top opening type of easement window, making it possible to secure the greatest benefit therefrom at a minimum cost.

Window structures, embodying my latching device, have the added advantage that the entire sash may, when not permanently mounted by hinges, be removed to secure full size window openings. A window sash secured by any latching device may be completely removed Without need for head Vroom above the top of the window frame itself.

Itshould be noted also that the working parts of the latching mechanism do not, at any time. extend any appreciable distance inwardly beyond the inner surface of the sash or window frame and, therefore, are never in the way.

Furthermore the mounting of my improved latching device is extremely simple, requiring the installation of only four wood screws.

Y Although I have described a specific embodiment of my invention, it is apparent that modiilcations thereof may be made by those skilled 4 in the art. Such modiiications may be made without departing from the spirit and scope of my invention as set forth in the appended claim.

I claim as my invention:

A three-position latch for use in combination with a window frame including spaced vertical frame members and a sash pivotally mounted to swing inwardly at the top thereof and recessed between the said vertical frame members, said latch comprising a generally U shaped bolt, one leg thereof being of a length substantially equal to the distance between the inner surface of the sash, when closed, and the inner edge of one of said verticalframe members. the said leg having a lateral projection at the end thereof, the other leg of said bolt providing a handle therefor, a keeper having a portion thereof adapted to revolvably and slideably receive the transverse portion of the bolt and secure the bolt to an inner surface of one of said vertical-frame members,

and a latching plate secured to the sash at a.

distance from the edge thereof substantially equal to the thickness of the said leg of the bolt, the latching plate having a portion thereof adjacent the edge of4 the sash spaced inwardly from the sash a distance suiicient to receive the lateral projection of the leg therebetween, the legs of the bolt being spaced apart a distance greater than the length of the said keeper by at least the thickness of the said leg, and the keeper also being spaced from the edge of the frame member adjacent the sash a distance at least equal to the thickness of the said leg of the bolt.
